LU-BRIOATING DEVlCE FOR RAILWAY-ems SPECIFICATION forming part of Letters Patent No. 402,952, dated May 7, 1889.

lie it known that 1, JAMES W. )h-UMY, a citizen of the United States, residing in Mariett'a, county of Cobb,.and State of Georgia, have invented certain new and useful improvements in Railway-tars, of which the following is a specification.

M y invention relates to railway-cars; and my invention consists in the combination with the car-axle boxes, of a pumpand connections, as fully set forth hereinafter, whereby to positively maintain a circulation of the inbricating material through the several boxes and a continuous supply of the lubricating material to the said boxes.

In the accompanying drawings, 'Figu re 1 is a sectional elevation of a railway-car truck and part of the platform of the car, illustrating my invention in connection therewith. Fig. 2 is a trmisverse section of one of the boxes, and Fig. 3 is a transverse vertical section of the pump illustrated in Fig. i. Fig. l is a longitudinal section of the axle-box.

A represents 'one of the boxes and A another of the boxes of a four-wheeled truck, which boxes contain bearings 2 i? for the journals (f the axles i, to which the wheels -.t arc attached, and the said boxes slide in guides upon the truck-frame it, which rests upon springs 5, of any suitable character, having their bearings upon the boxcs, and the plat.- form of the car has its bearing, as usual, upon the center beam, 8, of the truck.

Upon the truck is mounted a pump, l), of any suitable character, the same, as shown, being a cylinder-pump w ith a cylinder, 7, piston 8, piston-rod J, an inlet-pipe, to, at the upper end, and discharge-pipe ll, communieating with the lower end, and this pump is operated in any suitable manner, preferably by the rotation of the wheels of the truck-as, for instance, through an eccentric, it, upon one of the axles operating upon the lever 1 pivoted to the truck-frame extending over the eccentric and drawn downward by a spring, ]-l.

The piston 8 is perforated and provided with a valve, 15, which opens on the ascent. of l the piston, so that when the latt er moves down the piston will tend to expel the contents of l the ylinder from the lower end and to draw in a supply at the upper eno, which su p) passes below the piston upon the opening 01' the valve when the piston ascends.

'l'he pipes l) and i1 communicate with two maincondnoting-pipes, l7 and 1H, carried by the car, tin-conneetions being formed by lie)" blc continuations with the said pipes 10 and 11, which permit. the swinging of the truck withi'iut straining of the pipes.

llach axle-box ot' the truck and of the car, whatever may be the number of axles and trucks, is provided with an outlet port. orpipe, lit, at the lower end, and with-an inlet port or pipe, 2 at the upper end, and the ports 20 comu'iunicate through flexible pipes 21 with the main pipe ligand the ports it) through flexible pipes 2:3 with the main pipe 17.

As the piston descends, the oil or lubricant. at the bottom of each box is exhausted through the pipe 2'. and pipe 17 into the upper end of the pump, and as the piston ascends the oil passes through the lower end of the pump, and on the next. descent of the piston the oil. isforced through the pipe 11 and'pipe 18 into all of the pipes 21 and into the to of each box, and is thrown onto the journa or hearing in such manner as to absolutely insure the elt'ectivc lubrication of the journal. hy thus maintaining an enforced circulation ot' the oil from each box to a main 0; c ntral pump, and from the latter back to tlic seyeral boxes, I effectually prevent the boxes i'rom becoming heated. Thus each journal is'supplied with oil by the positive and forcible injection of a stream of oil upon the journal or its bearin Should the oil in any one oi. the

' boxes become gummy from any cause, it. is

speedily withdrawn and diluted by the larger body of oil in the pump-cylinder, and the it.- bricatiug quality of the oil in each box is maintained at as high a standard as that of the oil in the other boxes. No one of the boxes can be deprived of its oil by leakage-so long as there is any oil in the other boxes.

It will be evident. that the condnoting-pipes maybe differently arranged and connected with the boxes and pump in diiicrent ways witlnnlt departing from the main f atures of my i||vr.-nt.ion, and that there maybe an independent connect ion between each box and the pump, in which easethe pipes 21 and 22 would extend directly from each box to the cylinder, of the pump, as shownin' dot-ted lines, 5,5 1. 1

Without limiting myself to the precise-consgruct-ion and arrangement of parts shown, I alum- 1. The combination, with the axle-boxes of :1 railway-car, of a sin 1e pump communicating with each box 0ft 0 car at its upper: and lowerv parts to maintain a circulation of oil through the pump and through each box, the

pump being connected with one of the axles to be operated positively by the rotation thereof, subsiuutially as set; forth.

2, The combination, in a railway car, of a. pump communicating .with pipes 17 and 18,

' carried by the car, and a communication between the pipe 17 and the lower end of each axle-box of the car and between the pipe 18 and the upper end of each axle-lmx of the car,

substantially as set forth.

3. The combination of a car-body, one or more swinging trucks supporting the same, and pipes 17 and 18, carried by the body, a pump communicating through flexible pipes with the pipes 1.7 and 18, and A flexible pipe connecting the lower portion of each car-axle box and the pipe 17, and another flexible pipe connecting the upper portion of each car-axle box and (the pipe 18, substantially as set forth. 3

In testimony whereof I have signed my name to this specification in the presence of two subscribing witfiss. v
